Description
Technical field
The present invention relates to theme park moulding, more specifically, it is related to a kind of theme park external decoration moulding with solvent-free
Composition epoxy resin and the external decoration formative method using the composition epoxy resin.
Background technology
As a kind of novel tourist famous-city, theme park (theme park) is just with its unique cultural connotation, rich
Rich scientific and technological content and powerful amusement function attract more and more public tourists.Has been started from nineteen fifty-five DISNEY
Since one theme park truly, larger scale has been quickly formed on the U.S., Europe and Japan and other places.
With the opening of Shanghai Disney theme park, domestic theme park flourishes, the prosperity of theme park, drives
The development of theme moulding decorative material, traditional theme external decoration Modeling Material such as unsaturated polyester (UP), Site coagulation
Soil etc. cannot meet modern theme park modeling requirement.In the world of art of theme external decoration design, material is as performance
Gimmick suffers from different existence forms.In the landscape moulding of theme park, the moulding such as artificial hillock, imitation wood, feature wall are due to moulding
Novelty, traditional landscape Modeling Material such as unsaturated polyester (UP) overmolded moulding, is only limitted to small articles, it is impossible to realize disposable film forming
Thickness 13mm, and do not trickle, there are bubbles, smell is big, and the housing of packaging is spliced together, and matter is crisp, and intensity low durability is poor.
In addition, the turn over the mold type of traditional unsaturated polyester (UP), smearing release agent is wanted on mold, after demoulding, remover is cleaned up,
Otherwise subsequent coloring is influenced, it is not environmentally friendly enough when carrying out acid solution cleaning releasing agent, and complex procedures.Therefore, tradition is turned over
Modeling material unsaturated polyester resin material, there is matter is crisp, density is big, shock resistance is poor, durability is poor, trowelling application property is poor
The characteristics of, and smell it is big and not environmentally.
Invention content
Therefore, the purpose of the present invention is to provide a kind of new external decoration Modeling Material, that is, a kind of external decoration moulding is provided
With solvent-free epoxy resin composition, this solvent-free epoxy resin external decoration Modeling Material, light (dead weight is small) is environmentally protective
(0 volatilization), slipping is good without releasing agent, is easy to colored drawing and coloring, high tenacity, adhesive strength is high, and can be according to construction need
Field adjustment viscosity is wanted, application property is good.
It is a kind of using above-mentioned external decoration moulding solvent-free epoxy resin composition another object of the present invention is to provide
The method for carrying out external decoration moulding.
The problem of general solvent-free epoxy resin material easily trickles in itself there is also crisp, sticky, the thick painting construction of matter.
The method for carrying out toughening to epoxy resin at present has very much, for example, the methods of adding in plasticizer or toughener is modified it,
But tensile strength and shear strength can all decline, effect is not ideal enough；When being modified with liquid nitrile rubber, this elastomer
Epoxy resin toughened significant effect, but modified epoxy resin elasticity modulus and glass transition temperature reduction are more, should not use
In the occasion higher to deformation and temperature requirement；And it is poor to smear construction slipping, it is impossible to as landscape moulding.It is in addition, traditional
Solvent-free epoxy resin viscosity of material is high, and wire drawing, viscous knife be not smooth, and tool, mold, facility etc. are easily polluted in work progress,
Construction tool is difficult to clean after construction.
The present inventor is for theme park external decoration moulding, to solvent-free ring by traditional solvent-free epoxy resin material
